<strong>gnetlist</strong> is a <em>netlisting</em>  tool, and is part of the <a href="geda-faq.html" class="wikilink1" title="geda-faq.html">gEDA (GPL Electronic Design Automation)</a> toolset.  It is used to extract information about electronic components and the connections between them from <em>schematic diagrams</em>,  which describe the logical structure of an circuit.  gnetlist outputs the <em>netlist</em> in a variety of formats that can be automatically processed by other tools, such as printed circuit board (PCB) layout tools or circuit simulators.
